Ptch, a new app from Dreamworks — yes, that Dreamworks — takes photos and videos from your iPhone and quickly stitches them into a poignant “film.”

Here is a Ptch I created of a trip to the park with my kids last winter. I tear up every time I watch it.

Here is another I made last night of Sandy’s recent impact on my area.

Both took less than three minutes to build and publish.

A standout feature of Ptch is that the photos and videos you are already taking with your iPhone, plus the ones you are sharing on Facebook, Twitter, Google+, Tumblr, Viddy or Instagram, are usable when building a Ptch. I had no intention of making a movie when I went to the park on that winter day with my children or while I surveyed the aftermath of the storm.
